kandi X-RAY | todd Summary
Traditionally, the tooling used by network engineers to confirm continued network operation after any kind of change to the network is fairly limited. After a change, a network engineer may run "ping" or "traceroute" from their machine, or perhaps call some application owners to ensure that their apps are still working. Unfortunately, there is a very big difference in network activity between a 3AM change window and peak user activity during the day.

QUESTION
I'm using express.js with mysql2.
When a duplicate entry error happens on insertion I get the error in the global error handler and that works as expected.
When I log it to the console, the error looks like this:
...ANSWER
Answered 2021-Jun-06 at 13:53I actually came up with a decent solution.
Because the sqlMessage will always be in the same format, I first split the sqlMessage into an array, and then extracted the value entered, and then I also extracted the field, but since the field is in a format "database.field_UNIQUE", I had to extract the field that is in between the "." and "_" characters.
The code looks like this:

QUESTION
I am working on assigning random priorities (i.e. high, medium, low) to a list for a ServiceDesk assignment.
Before that, I was wondering how to go about storing (and printing) an array in said priority queue. This is currently what I have.
*UPDATED CODE
...ANSWER
Answered 2021-Apr-18 at 02:33Sounds like you are asking for help on how to get started. You are asking for help on learning to learn. Here is how I would approach your problem:
Apparently you are supposed to use a priority queue.
- Write a tiny program that makes a priority queue and stores strings into it, then prints them out.
- Define a class and store instances of that class into the priority queue instead of strings.
- Modify the sort criteria on the priority queue and notice that the printed sequence changes according to the sort criteria.
- Write a function that creates one class instance with random values.
- Write a function that creates all 100 class instances.
- Declare victory.
QUESTION
I'm trying to write an efficient stringification routine for logging dicts, but want to redact certain values based on key names. I see that JSONDecoder
provides the object_pairs_hook
which provides key and value, but I don't see a corresponding hook for JSONEncoder
- just 'default' which only provides value. In my case, the values are just other strings so can't base the processing on that alone. Is there something I missed?
For example, if I have a dict with:

QUESTION
I'm very much a beginner when it comes to database relationships hence what I suspect is a basic question! I have two database tables as follows:
Projects
- id
- company_id
- name
- etc...
rfis
- id
- project_id (foreign key is id on the Projects table above)
- Number (this is the column I need help with - more below)
- question
The relationships at the Model level for these tables are as follows:
Project
...ANSWER
Answered 2021-Mar-21 at 02:48What I understood is that you want to set the value of the "number" field to "1" if it's a new project and "increment" if it's an existing project. And you want to automate this without checking for it every time you save a new row for "RFI" table.
What you need is a mutator. It's basically a method that you will write inside the desired Model class and there you will write your own logic for saving data. Laravel will run that function automatically every time you save something. Here you will learn more about mutators.
Use this method inside the "RFI" model class.
QUESTION
When the 'Add Customer' Button is pressed in MainActivity.kt a new Activity is started for Result, CustomerActivity.kt. CustomerActivity opens up Fragment (ListFragment.kt) which contains a list of all the Customers in the Room Database.
When a Customer is clicked on, another Fragment is opened. In UpdateFragment.kt, all the customers information is displayed and a button "Choose Customer". Once clicked, an Intent is created and the Customers information is added to the Intent. The Main Activity is opened again and with it the selected customer information passed in the intent.
How can I open the Intent for its information from UpdateFragment.kt in MainActivity.kt? And gain access to the customer information that was passed with the intent? Currently I am able to create an intent with the customer information in UpdateFragment.kt and open MainActivity.kt but I do not know how to access the intent in MainActivity.
MainActivity.kt

Answered 2021-Mar-09 at 09:07I did not read everything you wrote but in your Activity class, you are checking the result code which is wrong. Change it to request code
